(1) actively transport molecules in an organism

Explanation:

ATP (adenosine triphosphate) is a nucleotide made of the nitrogenous base(adenine), the sugar(ribose) and three phosphate groups which are covalently linked togther and attached to ribose.

ATP fuels cellular activities by transferring a phosphate group as seen in the attached image to a different molecule (this process is refereed to as phosphorylation).

the answer is yes, they are born/created, then they grow to their limit then produce offspring, then die.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
